Group 1 winners Catchy, Invader, The Mission and Summer Passage are among a huge 327 entries for the $2 million Group 1 Caulfield Guineas (1600m) on October 14.

An increase in prizemoney from $1 million for the three-year-old feature has resulted in the prospect of a high quality edition of the race with the 327 nominations just two short of the 2016 figure.

Filly Catchy, who is also entered for the Group 1 Thousand Guineas (1600m) on the same day, is one of the elite level winners having taken out the Group 1 Blue Diamond Stakes (1200m) during her two-year-old season. She is one of 35 entries for Lindsay Park trainers David and Ben Hayes and Tom Dabernig.

Joining her in the list of nominations is Group 1 Sires Produce (1400m) winner Invader for trainers Peter and Paul Snowden.

The Paul Perry-trained Group 1 Champagne Stakes (1600m) winner The Mission is another notable entry, while Lance O'Sullivan and Andrew Scott's Summer Passage brings New Zealand form to the table having won the Group 1 Sistema Stakes (1200m).

Tony McEvoy's unbeaten colt Royal Symphony is also among the nominations after winning all three races during the winter including the Taj Rossi Winter Series final (1600m) at Flemington.

“There is no doubt that the huge number of Caulfield Guineas entries (327) received today is in direct relation to the rise in race prizemoney which has doubled to $2 million as part of major prizemoney increases announced in May,” Racing Victoria Executive General Manager – Racing, Greg Carpenter, said.

“It is one of the strongest Caulfield Guineas we’ve ever seen with the leading stars of the autumn such as Catchy, The Mission, Invader, Summer Passage and the story of the winter, Royal Symphony, among the leading contenders to take home the $2 million purse and then pursue the Cox Plate two weeks later.”
